Open procedures for rectal prolapse
Open operations for rectal prolapse
• Perineal operations inferior to abdominal
procedures, but definite role
• Delorme’s procedure – simple but high recurrence
rate, can be repeated
• Perineal rectosigmoidectomy – more complex but
lower recurrence rate
• “If the patient is fit enough and life expectancy >
5yrs abdominal approach preferred”

Open operations for rectal prolapse
A range of possibilities:
• Exclusion procedures
• Pelvic floor repair
• Anterior or posterior rectopexy
• Resection – alone or with rectopexy
Open operations for rectal prolapse
Sigmoid exclusion procedure (Lahaut’s
operation)
• Rectum fully mobilised in pelvis
• Rectosigmoid sutured to posterior rectus
sheath
• Sigmoid extra-peritonealised behind rectus
muscle
Open operations for rectal prolapse
Lahaut’s operation
• 33 pts
• 1 death (3%)
• No recurrences
• 11 of 12 pts improved continence
• One faecal fistula (?ischaemic)
• One obstruction

Open operations for rectal prolapse
Pelvic floor repair via the abdomen
• Full anterior and posterior mobilisation of the
rectum
• Repair of pelvic floor posterior (originally ant and
post) to rectum
• Difficult access
• Pelvic floor thin and attenuated
• Largely replaced by rectopexy

Open procedures for rectal prolapse
Rectopexy
• Probably the operation of choice
• Recurrence rates approx. 2%
• Continence restored in 60-80% with rectopexy
alone
• How should rectum be fixed?
• When should resection be added?
Open operations for rectal prolapse
Anterior rectopexy (Ripstein procedure)
• Full mobilisation of rectum
• Fixation to sacral promontary by sling
(polypropylene, teflon or fascia)
• Principle complication – fibrous stricture

Open operations for rectal prolapse
Posterior rectopexy
• Posterior aspect of fully mobilised rectum
attached to sacrum
• Lateral peritoneum divided, posterior
mobilisation to tip of coccyx, division of
lateral ligaments
• No anterior restriction, distensible rectum
• Mesh to sacrum and lateral aspects rectum
Posterior rectopexy
Posterior rectopexy
Method of fixation
• Teflon
• Polypropylene (marlex)
• Polyvinyl alcohol sponge (Well’s procedure)
- infection (recurrence)
• Vicryl
• Gore-Tex
• SIMPLE SUTURES
Sutured posterior rectopexy

• Sigmoid or partial rectal resection (n=113)
• Incontinence:
- Improved 23 (20%)
- Same 13 (11%)
- Worse 10 (9%)
• Sepsis morbidity: 52% after “low” and 19% after high

Resection Rectopexy
• Aims to achieve low recurrence rates and avoid
long term constipation
University of Minnesota series
• 138 pts
• Anastomotic leaks in 5 (4%)
• Recurrent prolapse in 2 (1.4%)
• Continence improved in all but 1 pt
• Constipation improved in 56% same in 35% worse
in 9%

Open Approaches for Rectal Prolapse
Summary
• Lower recurrence rates but higher morbidity
than perineal procedures
• Fixation superior to pelvic floor repair, or
resection alone
• Posterior fixation superior results
• Sutures alone comparable to mesh fixation
• Less constipation with concomitant
resection
Open Approaches for Rectal Prolapse
Conclusions
Sigmoid resection with sutured rectopexy
offers:
• Low risk of recurrence
• The long term avoidance of constipation
• PROCEDURE OF CHOICE
• (why not laparoscopically?)
